A good book would be Don Casey's This Old Boat. IIRC, it will talk about doing what you need.

Basically, you'll want to strip the bottom, grind out the blisters, fill them with thickened epoxy, barrier coat the bottom, and then paint with anti-fouling paint.

You'll probably want to have someone sodablast the bottom, since it will get rid of all the paint down to the bare gelcoat, and be the most cost-effective way to do it IMHO.


Random Orbital Sander w/ 80 or 100 grit discs
Plastic containers for mixing epoxy
paint mixing sticks, for mixing epoxy and bottom paint
paint rollers (foam for epoxy and 3/16" for bottom paint and barrier coat)
Tyvek bunny suit (to protect you from bottom paint/epoxy/ground fiberglass
Full face respirator mask with VOC and P95 cartridges (same as bunny suit)
Nitrile or vinyl gloves (same as bunny suit)

Materials Needed:

Epoxy (MAS, System Three or West Systems)
High-density filler (Colloidial silica or cabo-sil is best for this purpose)
Interprotect 2000E barrier coating (or you can use epoxy, but I prefer the IP2000E)
Bottom paint suitable for your area

If you need more detailed info, please let me know.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
